Is Intermittent Fasting safe for everyone?
The honest answer is: no.
These are seven conditions where Intermittent Fasting may be risky, and it is important to understand each one before following the trend.
Pregnancy and Breastfeeding
Intermittent fasting can reduce milk supply, lower daily energy levels, and affect nutrient availability for both mother and baby. Pregnant and breastfeeding women require steady nutrition, so fasting can be unsafe.
Diabetes Patients Taking Medication or Insulin
Fasting can lead to serious drops in blood sugar, also known as hypoglycemia. People with diabetes should follow Intermittent Fasting only if their doctor approves and monitors their condition.
Low BMI or Unexplained Weight Loss
Those who already have a low BMI or are losing weight without trying may experience further nutrient deficiency, weakness, and muscle loss with fasting.
Thyroid Issues, Especially Hypothyroidism
Intermittent fasting may increase cortisol levels, which can interfere with thyroid hormone balance. Anyone with thyroid problems should practice caution and seek medical guidance.
Digestive Problems
Individuals dealing with acidity, GERD, stomach ulcers, or chronic gastritis may experience worsening symptoms when staying hungry for long hours. Fasting increases acid production and discomfort.
Heavy Workouts or High Physical Activity
People who perform intense workouts or have physically demanding routines need higher calories and consistent fuel. Fasting for long periods may lead to low energy, reduced performance, and muscle loss.
PCOS, High Blood Pressure, Irregular Periods, Anemia, or Migraine-Prone Individuals
Those with hormonal imbalance, blood pressure issues, low iron levels, or migraine triggers should follow Intermittent Fasting only with professional guidance. Skipping meals can worsen fatigue, headaches, and hormonal symptoms.
